To all whom it may concern:

Be it known that ll, ROBERT A. READ, of

the city of Toronto, in the county of York,

Province of Ontario, Canada, have invented certain new and usefulImprovements in Cloth-Cutter Guards, of which the following is' aspecification.

. This invention relates to cloth cutters ernploying a verticallyreciprocating knife and a presser foot which holds the fabric beingcutdownagainst the base on `which the mal attain my object by means ofthe co1i` structions hereinafter described and illustrated in theaccompanying drawings in which- Figure 1 is a side elevation showingpart of a cutter provided with my guard; and

Fig. 2 a plan view of the same parts.

ln the drawings like numerals of reference indicate corresponding partsin the different figures.

l is the base of the machine from which extends the standard 2 on whichthe `frame 3 of the device is supported. rlhe knife l runs in thestandard as shown with its edge projecting. 5 is the presser barsuitably guided in bearings 6 on'part of the frame 3. The presser barand its arrangement form no part of the present invention and may be ofany ordinary type..

Secured to the lower part of the presser bar is a clamp 7 and to theupper end is secured a clamp 8. To the lower clam is secured a bent wiremetal guard 9, which extends rearwardly and overlaps the knife on theleft hand side thereof when the appa ratus is in the position in whichit is used. The forward edge of this guard is formed as a rod l0. rlhisrod passes through a hole in the upper clamp 8 and is thus held inposition. This gives a suitable support for the guard withoutinterfering in any way with the other parts ofthe machine. IThepecication of Letters Patent. application med april s, isis.

Patented ov.. d, serial No. ascesa guard being supported atthe extremeends L" ofthe presser foot, the vertical adjustment of the latter is inno way interfered with. 'lhe edge of the knife above the presser foot`is thus completely protected at the only side on which it is accessibleby the hand of the operator, who frequently finds it necessary to pressor hold down the goods justas they pass under the presserfoot.`

'llhe presser foot is of peculiar construction. A. toe ll is extendedforwardly from the presser foot for some considerable distance inahorizontal direction and the end l2 is turned up slightly so that thetoe will ride easily over the mate-rial being cut. When the presser footreaches the edge of the pile of fabric being cut, the toe will projectover the edge. llt is quite common for a cutter to work with his lefthand in front of the presser foot with the fingers on the fabric at `onesideand the thumb on the fabric at the other side `of the presser footholding down the fabric. When the edge of the pile `of fabric isreached, unless the operator is alert, his hand may drop and be `caughtby the knife below the presser foot. rllhe projecting toe prevents this,as,

the hand will drop on to the toe as soon as the support of the pile offabric beneath the nger tips is removed, and thus the hand is held upand prevented from contacting with the knife. l` his projecting toe thuscooperates with the guard 9 in the prevention of accidents to theoperator.

What lf claim as my invention is l. The combination with a cloth cutterprovided with a frame, a base, a standard connecting the frame and thebase, a vertically reciprocating knife, a presser foot, a presser bar towhich the presser foot is connected and upper and lower guides for saidbar, of a guard comprising anv open metal p provided with a frame, abase, a standard connecting the frame and the base, a verticallyreciprocating knife, a presser foot, and a suitably guided presser barto which the presser foot is connected, of alguard located in front andto one side of the knife above the presser foot, a rod extending up fromthe front side of the guard; a clamp i secured to the lower end of thepresser bar to which the lower end of the guard is secured; and a clampsecured tothe upper end of the presser bar embracing the upper end ofthe rod.

The combination with a cloth cutter nprovided with a frarne, a base, astandard connecting the frame andthe base,` avertically reciprocatingknife, a presser foot, and facsuitablyyguided presser bar to which 'thepresser foot isjconneeted Iand upper and lower guides for saidbar, of aguard located in 'front land to one side of the knife above the presserfoot; and supports for'theguard extending laterally yand connect-ed tothe presser 'bar above the upper and below the lower guidethereof.- f

4. The combination with -a cloth 'cutter pro-vided with a frame, a base,a standard connecting the franieand'the base, a Vertically'reciprocating knife, apresse'r foot, and a suitably gui'dedpresserbar'to whichfthe presser foot is connected, of a guard located in frontand to one side of the knife above the presser foot;l a rod extending upfrom thefront side of the guard; a laterallyv eX- tending`-clainp"secured to the lower Ven'd of the presser bar Ito which thelowerend of the .guard is secured; rand a laterally extending clampsecured to the upper end of the presser bar embracingthe upper 'end ofthe rod.

'C`opies`f this patent may he obtained for 5. The combination with acloth cutter provided with a frame, a base, a standard connecting thefraine and the base, a ver tically lreciprocating knife, a presser foot,and a suitably7 guided presser bar to which thepresser foot is connectedand upper and lower guides for said bar, of a guard located in front andto one side of the knife above the presser foot having its lower edgeinclined downwardly from the front to the rear; and supports for theguardconnected to the presser'bar above the upper and below the lowerguide thereof.

6. The combination with a cloth cutter provided with frame, a base, astandard Connecting the frame and the base,a vertically reciprocatingknife, a Apresser foot formed with a forwardly projecting horizontal toewith upwardly inclined forward end, a suitably guided presser'bar towhich the presser foot isconnected and upper and lower guides for saidbar, of'aguard located in front and to one side of the knife above thepresser foot; and supports for the guard extending laterally andconnected to the presser bar .above the upper andbelow the lower guidethereof.
